Hi, Habr! This is rather not an article-explanation, but an article-reasoning about continuity and the very pulp, I hope, will be in the comments.
Due to the fact that the business continuity has become a fashion trend, something like nanotechnology, innovation and import substitution, it's time to decide what BCP is and what DRP is, what is the difference and why BCP and DRP is like that joke "not a husband and a wife, and four completely different people. "
BCP (business continuity plan) - a business continuity plan. It contains a detailed plan of what needs to be done to restore business processes.
DRP (disaster recovery plan) - disaster recovery plan. Contains a detailed plan for the restoration of infrastructure. IT infrastructure is usually meant, but it can be a variety of mechanisms, vehicles and buildings.
')
Both plans will be used immediately after a crisis or catastrophe occurs. Both plans contain a set of instructions and a description of the people who must follow these instructions. Both plans should be tested periodically to ensure that the plan is viable. Both plans should be developed based on business requirements *. Perhaps this is where the similarities end and the differences begin.
DRP is a recovery plan. If the warehouse burned down, then there is a spare warehouse for such a case. If masks shows arrived at the data center, there is a backup data center. If the car broke down - there are spare parts for repair. Or reserve car. Depending on the requirements of the business, which we will discuss in another article.
BCP is a business continuity plan, and more specifically, a specific business process. BCP allows you to continue the business process after a disaster or crisis situation as quickly as is necessary for the business.
In the event of the failure of an office building, DRP will describe how to quickly launch a new office building. BCP will describe how to organize the remote work of employees. In the event that remote work is not possible, the BCP will include DRP, but not vice versa. And somewhere at this moment there will be a feeling that this is the same thing, but it is not.
In the event of a data center failure, for example, a telecommunications company, the BCP plan will describe the process of moving to a backup data center and related communications. DRP will describe the relocation of each system. In fact, in this case, the BCP plan includes many DRP plans.
BCP is created and tested together with business representatives. DRP is created and tested inside the IT department.
Very interested in the opinion of practitioners who pick up the confusion in terminology in continuity.
- * - Business requirements are exactly the requirements from the business, and not reflections within the IT department, what the business requirements might look like.
